Title: Change commons-dbcp to a compile-time dependency

Tomcat, as packaged by Ubuntu, seems to provide this but it can't be relied upon in other environments.

For example, without this it fails to run on a vanilla tomcat install downloaded from apache.org. The error is rather annoying to track down since it presents as a NullPointerException.
